Question

a mass of a planet jupiter is 1.9*10^27 kg and that of the sun is 1.99*10^30 kg.the mean distance of the sun from jupiter is 7.8*10^11m.calculate the gravitation force which the force exerts on jupiter.

Answer 1

gravitational fr =Gm1×m2/r²
 G=6.673×10 to the power -11
m1= 1.9×10∧27
m2=1.99×10∧30
r=7.8×10∧11
 f=gm1m2/r²
f=6.673×10^-11  ×1.6×10^27× 1.99×10^30   /(7.8×10^11)² 
Using these values, we get the force between the sun and Jupiter to be 4.16×1023N

Answer 2

Answer:

Gravitational force is given by:

$F = G \frac{M m}{d^2}$

G is the gravitational constant, M and m are the masses of two bodies and d is the distance between them.

It is given that, mass of Jupiter, M = 1.9 × 10²⁷ kg

Mass of sun, m = 1.99×10³⁰ kg

Distance between two, d = 7.8 ×10¹¹ m

G = 6.67×10⁻¹¹m³ kg⁻¹ s⁻²

$F = 6.67\times 10^{-11}m^3 kg^{-1} s^{-2} \frac{1.9 \times 10^{27} kg\times 1.99\times 10^{30} kg }{(7.8 \times 10^{11})^2 m^2}=4.14\times 10^{23} N$
